1-7.4 PS/2 Keyboard and Mouse Interface
PS/2 keyboard and mouse connectors are located on the back panel of the
motherboard. The +5 V lines to keyboard and mouse connectors are
protected with a fuse that prevents motherboard components from being
damaged when an over-current condition occurs.
¿
Note
The mouse and keyboard can be plugged into either PS/2 connector.
Power to the computer should be turned off before a keyboard or mouse is
connected or disconnected.
The keyboard controller contains code, which provides the traditional
keyboard and mouse control functions, and also supports Power On/Reset
password protection. Power On/Reset password can be specified in the
BIOS Setup program.
The keyboard controller also supports the hot-key sequence
<Ctrl><Alt><Del>, software reset. This key sequence resets the
computer’s software by jumping to the beginning of the BIOS code and
running the Power On Self Test (POST).
1-7.5 Infrared Support
The IR connection can be used to transfer files to or from portable devices
like laptops, PDAs, and printers.
